Exploring Geographic Information Systems

This exploration of geographic information and geographic information systems (GIS) expands the discussion beyond the normal input-processing-output sequence. It begins by examining the manipulations that support analytical uses of GIS, including measurement and frameworks, representations, data quality, transformation and operations, parametric mapping, simple logic and overlay, taxonomy, distance transformations and surfaces. It then moves on to discuss operations that connect the practical exercises in the book to professional applications of GIS techniques in bureaucratic, social and cultural contexts.The inexorable progression of time and the inability to turn back the clock lead to
the most prevalent view of time as ... of cycles comes from the connection
between the spatial realm and the temporal, not because the time actually
repeats. ... Applying this view to geography, Hagerstrand (1970) developed the
highly graphic view of time as an additional spatial dimension. He created a three
-dimensional diagram in which the life histories of people interact in time and
space (Figure 1-1).
